Have you noticed gross, black streaks lining your roof as the weather gets warmer? These dark spots aren’t dirt and mold building up, you could be dealing with algae. While not extremely dangerous, roof algae can still cause your shingles to fall off. But, where does it come from? We have some answers below: 

Weather and Environment 

Depending on the location, algae growth is more common in coastal areas that can reach high humidity levels. Northeastern United States can often see a moderate amount of growth on their roofs, especially in spring and summer. Wherever high humidity lives, algae is bound to follow as moisture is it’s biggest encourager of growth.

How Algae Spreads

Algae spores are airborne, which means it can travel from item to item once formed. It can even stick to your clothes or pets! The worst part is that once one roof in the neighborhood has these black streaks, the rest of the houses may get them too. 

How To Get Rid Of The Streaks

While it might seem overwhelming, the process of getting rid of these black streaks is easy. All it really takes is a simple roof cleaning! Unfortunately, there aren’t very many options for permanently getting rid of algae. However, regular maintenance will make sure it doesn’t build-up.
